PROBLEM TO BE SOLVED: To provide a cutting method by a single wire type wire saw and a single wire type wire saw which can eliminate mechanical elements for supporting a pair of grooved guide rollers on the extension of a processing feed direction of a workpiece, and increase the length of the cuttable workpiece.SOLUTION: A single wire type wire saw 1 rotatably supports a pair of support arms 8 connected respectively to roller shafts 5 of a pair of grooved guide rollers 2 for stretching a wire 3, and comprises a movable operation shaft 9. In the process of processing and feeding a workpiece 4 relatively to the wire 3 and cutting the workpiece 4 by the running of the wire 3, in the middle of the cutting of the workpiece 4 and at the time of changing a processing feed direction, the operation shaft 9 is moved along an arc whose center is the central axis of the wire 3 in a cutting area. At the same time, the support arms 8 are rotated around the operation shaft 9, and a wire support direction of the pair of grooved guide rollers 2 is made to face the processing feed direction. |
